Declarations of war during World War II

Animated map of the European theatre of war during WWII

This is a timeline of declarations of war during World War II.

A declaration of war is a formal act by which one nation goes to war against another. The declaration is usually the act of delivering a performative speech or the presentation of a signed document by an authorized party of a national government in order to create a state of war between two or more sovereign states. The official international protocol for declaring war was defined in The Hague Peace Conference of 1907 (or Hague II).[1] For the diplomatic maneuvering behind these events, which led to hostilities between nations during World War II, see Diplomatic history of World War II.

## List of war declarations

[edit]

Below is a table showing the outbreak of wars between nations which occurred during World War II. Indicated are the dates (during the immediate build-up to, or during the course of, World War II), from which a de facto state of war existed between nations. The table shows both the "Initiator Nation(s)" and the nation at which the aggression was aimed, or "Targeted Nation(s)". Events listed include those in which there were simple diplomatic breaking of relations that did not involve any physical attack, as well as those involving overt declarations or acts of aggression. In rare cases, war between two nations occurred twice, with an intermittent period of peace. The list here does not include peace treaties or periods of any armistice.

Key to type (fourth column):

A | Attack without prior, formal declaration of war;
C | Declaration and/or attack without standard, formal procedure, sometimes preceded by a casus belli thus fait accompli;
U | State of war arrived at through use of ultimatum;
W | Formal declaration of war made.

1939-09-01 |  Germany |  Poland | A | German attack began at 4:44 a.m., Berlin and Warsaw time.[2][better source needed][3][4] Germany claimed that the attack was defensive, citing the Gleiwitz incident, which was actually a false flag attack.[5] | Invasion

1939-09-03 |  United Kingdom
Australia
New Zealand
India
Southern Rhodesia
Tonga
Transjordan |  Germany | U[3][6] | At 11:15 a.m. London time,[7] British PM, Neville Chamberlain publicly delivered his Ultimatum Speech.[a][6][8] As the Statute of Westminster 1931 was not yet ratified by the parliaments of Australia and New Zealand, the British declaration of war on Germany also applied to those dominions. Tonga was not a British dominion, instead, as part of the British Commonwealth (a protected state of the UK and the British Empire) declared war separately, alongside Britain (since it administers their foreign affairs).[9] | British declaration

1939-09-10 |  Bahrain
Canada
Oman |  Germany | W[3][6] | Canada's declaration several days after that of the United Kingdom is seen as a watershed moment in Canadian home rule and sovereignty.

As for Bahrain, given its status as a protected state of the United Kingdom, it was technically at war as of Britain's declaration, this is an acknowledgement of the declaration of war by Britain (due to coercion by an advisor),

Oman, under British influence, is coerced to participate in the war effort.

## Notes

[edit]

1. ^ Included in the speech: "...This morning, the British Ambassador in Berlin handed the German Government a final note, stating that unless we heard from them by 11 O'clock that they were prepared at once to withdraw their troops from Poland a state of war would exist between us. I have to tell you now that no such undertaking has been received and that consequently this country is at war with Germany..."
2. ^ The state of war was not recognized by, or formally ended until 1957, when Japan concluded a separate peace treaty in order to establish diplomatic relations with the Polish People's Republic. The Polish government-in-exile never recognized the peace treaty and remained in a technical state of war with Japan until it disbanded in 1991, following the fall of communism in Poland.
